Major Hazard Standard MHS 03 - Aviation Standard documen Revision 3 issued 20 August 2001 ** Uncontrolled copy. Use latest revision ** Guidance should be obtained from WMC’s aviation consultants on the acceptability of aircraft proposed for inspection patrols. Air Crew Single engine aircraft shall be crewed by a pilot and an observer. Multi engine aircraft shall be crewed by two pilots and an observer. Pilots shall have a minimum experience level of 2000 hours in command of the category of aircraft used for the survey. Pilots shall be line checked on low level survey flying. Where pilots have not undertaken such operations in the preceding 12 months, a line check flight is required before the pilot is used on the inspection patrol. Instructions to Flight Crew The flight crew shall be briefed on their respective roles for the inspection patrol and on the importance of teamwork in this specialised task. The pilot shall focus on maintaining the aircraft in a suitable position for optimum inspection visibility for the observer and on observing for hazards to the flight operation. The observer shall focus on inspection of the pipeline and alerting the pilot to plotted obstacles along the pipeline route. Flight Time Limits Low level flight time should be limited to a maximum of 6 hours. The time for the inspection patrol should not exceed 8 hours. Passengers Passengers shall not be carried on aircraft conducting aerial pipeline inspections. Specific Requirements for Aerial Operations on Pastoral Stations The following specific requirements apply to aerial operations on pastoral stations. This includes but is not limited to mustering, spotting and baiting. Aircraft Aircraft used in support of pastoral operations shall be appropriate to the task being performed and shall: • be capable of safe operation at slow speeds at low altitudes • have high all round visibility capability Guidance should be obtained from WMC’s aviation consultants on the acceptability of aircraft proposed for pastoral operations. Air Crew Pilots shall have a minimum experience level of 2000 hours in command of the category of aircraft used for the service and shall have the correct endorsements for the aerial activity to be performed. Aerial mustering operations shall only be conducted by pilots who have a current aerial mustering rating on the category of aircraft used. For operations below 500 feet above ground level, pilots shall hold a low level endorsement for the category of aircraft used and shall have a minimum of 500 hours in command of low level operations. Prior to commencement of any low level operation, pilots shall have had 10 hours in command of low level operations within the preceding 90 days and 50 hours in command of the aircraft type within the preceding 90 days. Instructions to Flight and Ground Crew Prior to the start of aerial work in support of pastoral operations, the WMC pastoral station manager shall brief the personnel involved on the conduct of the work including but not limited to: • individual roles and responsibilities • authority to change the scope and conduct of the work • locations of all sites included in the planned work • number and location of ground support crews the type of transport to be used by the ground support crews • the availability and standard of airstrips • communications equipment and protocols • fuel supply and fuel quality control • the location of any wires, obstructions or other hazards to aircraft • the search and rescue procedures actions in the event of an emergency • the location and type of first aid equipment available. Flight Time Limits Low level flight time should be limited to a maximum of 6 hours. The total flying time should not exceed 8 hours per day, including the time for any positioning flights.

Major Hazard Standard MHS 03 - Aviation Standard documen Revision 3 issued 20 August 2001 ** Uncontrolled copy. Use latest revision ** Last Light Operations in the vicinity of last light reduce safety margins through reduction of pilot’s perceptive skills and through increased activity by wild life near airstrips. It is also desirable to have daylight hours remaining in which to mount a search in the event of an aircraft accident. Adequate time margins shall be used to ensure that aerial tasks are completed prior to the onset of failing light conditions. Passengers Passengers are not to be carried on aircraft used for aerial work in support of pastoral station operations. Carriage of Firearms and Animals The carriage of and/or discharge of firearms from aircraft shall be permitted only in accordance with regulatory approvals and controls and by personnel qualified and licensed to do so. The carriage of animals in aircraft shall be permitted only in accordance with regulatory approvals. Specific Requirements for Helicopter External Lifting Operations Preparation Preparations for operations involving external loads by helicopters shall involve key personnel from the principal parties associated with the operation. This shall include : • WMC representative(s) for the operation • helicopter operator personnel • contractors whose equipment is to be moved • ground logistics personnel An inspection of the operational sites by aviation and logistics personnel during the planning stage is recommended. Guidance shall be obtained from WMC’s aviation consultants when planning external load operations using helicopters. Helicopter Requirements Helicopters used in external load operations may be either single engine or multi engine and shall : • be approved for external load operations by the relevant certifying authority • have an approved flight manual identifying the load performance limitations for the helicopter • have both electrical and mechanical release mechanisms • be equipped with external mirrors to observe the helicopter hook assembly Guidance shall be obtained from WMC’s Aviation Consultants on the acceptability of helicopters proposed for external load operations. Non-standard modifications to the helicopter shall be certified by the relevant aviation regulatory authority. Air Crew Pilots shall have a minimum experience level of 2500 hours in command of the category of aircraft used for the work and shall have the correct endorsements for the operations to be performed. Pilots and co-pilots shall hold an endorsement for helicopter external load operations on the appropriate weight category or type and have a minimum of 200 hours sling time. Where flight crew have not undertaken such operations in the preceding 12 months, a line check flight is required before a pilot is used on helicopter external load operations, on like operations to those proposed. Where non-pilot crew members are carried, they shall be trained in external load and winch operations as appropriate, and in helicopter loading, helicopter safety and emergency equipment and procedures. Passengers On Helicopters Passengers shall not be carried in helicopters conducting external load operations. Landing Areas The layout and dimensions of helicopter landing areas should conform wherever practicable to the requirements of ICAO Annex 14 - Heliports. Where the nature of the operation and the operating environment makes it impracticable to do this, landing areas should be established having consideration to the following factors: • the ability of the helicopter to make a safe landing in the event of engine failure on take-off or during final stages of landing • provision of a helipad surface of a size and of materials suited to the helicopter being used • provision of adequate rotor clearance from obstacles in the vicinity of the landing area • separation of personnel and vehicle traffic from the helicopter operating areas • elimination of loose materials in the landing area which would become airborne in rotor downwash SAF-MHS-03 Rev. 03 Docs: 55221 Issued: 20/08/01 Page 26 of 29
